DX8 Help

Choochoo22, jj604,and Charles

Thanks for the info on programming my DX8 radio. I have read post to RC Groups for years but never joined in on the discussions. On my first post I received info from California, Georgia, and Australia. Isn't the internet great.

RRutledge

It certainly is, having been in RC since 1963 when only a few books,model magazines, local hobby shops and a handful of others RCers were the only sorce of help really makes me appreciate the WWW and great RC sites such as RG Groups,HeliFreak,WattsFlyer and others. During the past 7 days I have reads likely to 1,000 post on FBL (Fly Bar Less) controls for helis and have mangaged to set one up from scratch ( Blade 400 was FB) and tweak a 450 which was allready setup FBL. Without the net I would still be stumbling around in the dark hunting for the light switch.

However, when you change the gain, it also changes the trim on the elevons. This is in 2D or 3D mode. Is that an expected result?

This is the behavior that you will see if you change your trims on your transmitter without resetting the trims on the Guardian. Basically, the Guardian is amplifying the stick offset you are inputting relative to the last known trim values. Note that even with perfect trims, if the model is in 2D Mode and is rotated to any orientation except for perfectly level, this behavior will manifest as well. Does this fit what you are seeing?

Great, now you need to put that in the manual for the Guardian. This is important to know since there is a definite consequence to NOT resetting your trims in the Guardian when you make radio trim changes. Please let us know when you revise the intructions in the manual and it can be downloaded. If you come back and say it's in the manual already then consider re-writing that section to make it clear because now it is NOT!

Need some help or advice. I am interested in finding out what some of you guys are doing out there to use the aux 1 and aux 2 connections on you OSD when you actually need a third when you have a guardian. In other words, I am ok with using a three position switch to manipulate the on screen menus (aux 1), and I currently have the (aux 2) input set for adjusting the master gain knob on the guardian. I am not sure the best way to set up the system as I would also like to be able to turn on the RTH with a switch as well. I have a 72 Mhz radio that is not PCM, can I still set throttle trim all the way down to engage the RTH that way? Or what are some of you guys doing that have 72 mhz non PCM?

after my deuces wild crashed and made a nice jig saw puzzle, I left it in the shop corner for a year. I just now rerbuilt it and modified the Deuces Wild wings to 16 in. longer with drooped tips [see pic.] and put a fy30A Flight stabilizer into it,
It fly's very smooth and it is no longer wild.

Guardin and Expo

Good morning:
It's 6am in Georgia and I can't sleep, so I am up asking questions about the guardin again. I am waiting on my guardin to arrive from Tower Hobbies mid October I hope and I won't to be ready when it gets here. yesterday you gave me some very good advice on how to program my DX8 radio.so Here's my question, I fly 3D type planes most of the time with 3 rates and expo programed into each surface, I will assum that the gain knob I will be using on Aux 3 will control the rate of surface movement, what about the Expo does it work with the Guardin. I have several planes with a 401 gyro attached to the ail surface, and it over rides the tripple programing in the radio.

I had a FY30A. The Guardian 2D/3D is a superior unit.
It is more effective, easier to set up, has a pc interface, weighs less, easier to mount, has auto oscillation suppression, sub modes such as head holding, and US support that speaks English.
Are you able to interface with the Fye Tech support team?

Needless to say I sold my FY 30 A and bought 2 guardian 2D/3D and will buy more.

Back on the need for a seperate UBEC....note that the PZ T-28 ESC is only rated for 700mah servo current Based on the data posted earlier on servo currents a single binded servo could exceed this. Something like a Dimension Engineering Park Bec would be much more suitable. Chek out the PZ ESC specs at http://www.e-fliterc.com/products/de...rodid=efla1030 which is also fitted to the Corsair and Radian if I am not mistaken. It would be great if someone with Telemetry could log servo current on a unstabilised flight and compare to a stabilised one doing similar manoeuvres. Has anyone tried doing this yet?

Also similar to the post a couple up from Mr Rutledge, I run dual aileron servos (for subtrim and differential reasons), multiple rates and also differential and rudder mixing in my DX8 radio (all set to specific values I like).

It looks like I use the Model Control Type as standard default, right?

I'm still confused why the Master Gain seems to be mapped backwards as described in the instruction manual...and I have read every post in this thread.
